The LW31 series cam switch is mainly used for kitting electric appliance switch cabinets, 3-phase asynchronous motors, and switching between main and auxiliary circuits. It is an ideal replacement for other rotary switches, and this series features an on/off and changeover function according to specific application cases.

Switches are small parts of machinery, but their quality and function should not be ignored. Cansen is a professional rotary switch supplier,founded back in 1981. Since then, we have been dedicated to the production of superior quality switches. To manufacture high-quality switches, we start by creating compatible switch fittings in which we design and produce each copper connecting sheet by ourselves. Knowing that safety is the most important factor in the design and operation of step cam switches, we inspect the switches multiple times during and after production, testing for things like mechanical endurance, proof tracking, fire resistance, and more. If you need help finding the right switch for your equipment, contact us for assistance.
